If a track team is running a relay race, shouldnt they be running the same distance? The fourth person who runs is going to be running alot more than everyone else.
<span>1. Make y the subject
a) 4y=12x+18
y = 3x + 4.5
b) 2x=7-3y
3y = -2x + 7
y = -2/3x + 7/3
2.
a) what is the equation of the line which passes through both (-2,-4) and (6,16)
slope = (16 + 4)/(6 +2) = 20/8 = 2.5
y = mx + b
-4 =2.5(-2) +b
-4 = -5 +b
b = 1
equation
y = 2.5x + 1
b) what is the equation of the line perpendicular to y= 1/2X + 7 passing through point (3,9)
</span>y= 1/2X + 7
slope = 1/2
slope of line perpendicular = -2
passing through point (3,9)
y = mx + b
9 = -2 (3) + b
b = 15
equation
y = -2x + 15
Answer: 6
Step-by-step explanation:
Eliminate the negative and change the operation.
4 + 1
Rewrite equation with parts separated
4 + + 1 +
Add whole numbers
4 + 1 = 5
Solve fraction
+ = ??
Find LCD of and . LCD = 15
+ =
Simplify fraction
= 1
Combine whole number and fraction
5 + 1 + = 6
h = 5
11 - 6 = H
so therefore h = 5
